RESUMEN
This study is to evaluate the potential value of serum GP73 in ancillary cirrhosis diagnosis. 150 cirrhotic subjects and healthy subjects were retrospectively analyzed, and the two groups were compared in terms of ChildâPugh grade. Serum GP73 was detected by enzyme-linked immunosorbent assay. Receiver operating characteristic curves were drawn to evaluate the diagnostic value of GP73, and the quantitative relationship between cirrhosis and GP73 was verified by logistic regression. The result showed in regard to serum biomarkers related to cirrhosis, the serum levels of GP73, TBIL, DBIL, and PT were higher and the ALB and PLT were lower in the cirrhosis group than in the control group (p = 0.000), and the area under the ROC curve of GP73 for diagnosing cirrhosis was 0.823 (p = 0.000), the cutoff value was 135 ng/ml, the sensitivity was 60.0%, and the specificity was 88.67%. Logistic regression analysis showed that GP73 > 135 ng/ml had an odds ratio of 11.735 (ß= 2.463, 95% CI: 6.432-21.411, p = 0.000) for diagnosing cirrhosis. Additionally, the ChildâPugh A, B, and C groups had different levels of GP73 (χ2 =17.840, p = 0.000). A pairwise comparison between the groups showed that there was a significant difference between grades A and B (p = 0.004) and between grades A and C (p = 0.002), but there was no significant difference between grades B and C (p = 1.000). We found serum GP73 levels were elevated in patients with cirrhosis. When the GP73 level was >135 ng/ml, the potential risk of a cirrhosis diagnosis increased approximately 12-fold.
